Grammostola pulchra/ Brazilian Black spiderling

The Brazilian Black tarantula (Grammostola pulchra) thrives at 70–75°F (21–24°C) with moderate humidity around 50–70%. It is a hardy, slow-growing terrestrial species that prefers a simple enclosure with deep substrate for burrowing.
🌡️ Temperature & Humidity
Ideal temperature: 70–75°F (21–24°C). They do well at typical room temperatures, so extra heating is often unnecessary unless your home is consistently cold.
Humidity: Medium levels, typically 50–70%. Provide a water dish and slightly moistened substrate, but avoid overly damp conditions.
Ventilation: Good airflow is important to prevent mold growth in the enclosure.
🏠 Enclosure Setup
Type: Terrestrial (ground-dwelling).
Size: Adults reach 5.5–7.5 inches leg span, so a terrarium around 12x12x12 inches (30x30x30 cm) or larger is suitable.
Substrate: Several inches of soil-like substrate (coconut fiber, peat, or spider bedding) to allow burrowing.
Decor: Hide (cork bark, half log) and water dish. No special lighting required.
🕷️ Species Traits
Temperament: Docile but skittish. Rarely bites; may flick urticating hairs if stressed.
Growth rate: Slow.
Longevity: Females can live 20–40 years, males around 6–10 years.
Behavior: Nocturnal, often spends time in burrows or hides.
📌 Care Tips
Keep enclosure dry with occasional light misting to maintain humidity.
Always provide fresh water in a sturdy dish.
Avoid handling too often—though calm, they can be stressed easily.
Feed appropriately sized insects (crickets, roaches) once or twice weekly.
In summary: Grammostola pulchra is one of the most beginner-friendly tarantulas thanks to its calm nature, tolerance of room temperatures, and long lifespan. A simple terrestrial setup with 70–75°F, 50–70% humidity, deep substrate, and a water dish will keep this Brazilian beauty healthy for decades
